We’re the UK’s Go-To Cleaning Company
High-Standard Cleaning with Compassion and Care.
Black mould isn't just unsightly. It's a health hazard that can seriously damage your property and wellbeing. At Scrubbed With Love, we've tackled thousands of mould problems across the UK, and we're here to share exactly how you can get rid of black mould safely and effectively.
Here's the truth: 1 in 5 UK homes has visible mould, and around 80-90% of household mould issues stem from excess moisture and poor ventilation. But with the right approach, you can remove black mould and prevent it from coming back.
Black mould, scientifically known as stachybotrys chartarum, produces mycotoxins that can cause serious health problems. Children in mouldy homes have 2-3 times higher asthma risk, and NHS data shows exposure triggers respiratory issues, coughing, and sinus congestion. The dangers of mould in bedrooms are particularly concerning, as this is where we spend a significant portion of time breathing in close quarters.
We've seen firsthand how black mould growing in homes affects families. The spores become airborne and contaminate your indoor air quality, making every breath potentially harmful. That's why we never recommend ignoring even small patches of black mould.
Before we show you how to remove mould, you need to understand what's causing mould to appear in the first place. Black mould thrives in environments with excess moisture and poor ventilation, so learning how to get rid of black mould starts with tackling these underlying issues. Here's what we commonly find:
Excess humidity: Mould grows best at 60%+ humidity levels. Your bathroom, kitchen, and poorly ventilated bedrooms become prime breeding grounds when moisture can't escape.
Condensation problems: When warm, humid air hits cold surfaces like windows or exterior walls, condensation forms. This creates the damp environments that black mould loves.
Poor air circulation: Areas where air can't circulate properly trap moisture and create perfect conditions for mould spores to settle and multiply.
Leaks and water damage: Any source of excess water provides the moisture black mould needs to establish itself and spread rapidly.
Never attempt to clean mould without proper safety precautions. We always tell our clients that safety comes first, and the same applies when you're tackling black mould yourself.
Protective equipment you need:
Area preparation:
Important warning: If the affected area is larger than one metre squared, or if you have health conditions like asthma or allergies, contact professional cleaning services. Some black mould outbreaks require specialist equipment and expertise.
Here's exactly how we approach black mould removal, broken down into simple steps you can follow:
Don't just clean what you can see. Black mould often grows behind surfaces, so check thoroughly. Look for:
We've tested countless products, and here's what actually works:
White vinegar solution: Mix four parts water with one part white vinegar. Vinegar kills 82% of mould species and is safer than bleach for most applications.
Baking soda paste: Mix baking soda with warm water to create a thick paste. This works brilliantly on stubborn patches and helps prevent mould returning.
Mild detergent solution: For lighter infestations, a solution of mild detergent and warm water can be effective.
Commercial mould killer: For severe cases, use products specifically designed to remove black mould. Always follow the manufacturer's instructions.
Fill a spray bottle with your chosen cleaning solution. Spray the affected area thoroughly, but don't over saturate. Let the solution sit for at least one hour to penetrate and kill the mould properly.
Using a brush with stiff bristles, scrub the mouldy area thoroughly. Work in circular motions and apply elbow grease to ensure you get rid of all the mould, not just the surface layer.
For bathroom sealant or other non-porous surfaces, you might need to remove and replace the sealant entirely if the black mould has penetrated deeply.
Wipe the area completely dry with a damp cloth, then immediately dry with a soft cloth. Any remaining moisture will allow mould spores to regrow in just 24-48 hours.
Make sure the area is completely dry before considering the job done. We can't stress this enough – moisture is your enemy in preventing mould returning.
Bleach limitations: While bleach might seem like the obvious choice, it only removes surface-level mould on non-porous materials. On porous surfaces like plaster or wood, bleach can't penetrate deep enough, and the mould often returns stronger than before.
Avoid mixing products: Never mix different cleaning products. This can create dangerous chemical reactions and compromise your safety.
Don't use too much liquid: Over-saturating the area with any cleaning solution adds more moisture, which can make the problem worse.
Removing existing mould is only half the battle. Here's how to prevent mould growing back:
Reduce condensation:
Improve ventilation:
Control humidity:
Regular maintenance:
Sometimes, despite your best efforts, black mould problems are too extensive or keep returning. Here's when you need professional help:
Professional mould removal services have access to industrial-grade equipment, protective gear, and specialized techniques that aren't available to homeowners. We also understand building regulations and can identify underlying causes that might not be obvious.
Many people postpone dealing with mould because they think it's just a cosmetic issue. Here's what that delay really costs:
Health implications: Ongoing exposure can cause serious breathing problems, skin irritation, and worsen existing conditions like asthma. Children and elderly family members are particularly vulnerable.
Property damage: Mould damage can reduce property value by up to 20%. Most insurance policies exclude mould damage unless it's from a specific insured event.
Legal issues: For landlords, failing to address mould can result in fines under the Homes (Fitness for Human Habitation) Act 2018. Tenants have legal rights to demand action.
Spreading problems: Mould doesn't stay contained. Spores travel through air conditioning systems and can contaminate your entire property if left unchecked.
We understand that many homeowners want to tackle mould removal themselves, and in many cases, that's perfectly reasonable. Small areas of surface mould can often be handled with the right approach and safety precautions.
However, our experience has shown us that certain situations require professional intervention. We have specialized equipment that can detect hidden moisture sources, industrial-grade air purification systems, and the expertise to ensure the job is done safely and completely.
